Collaboration services promise to improve the engagement and effectiveness of humans across geospatial, temporal, and organizational boundaries. However, there also are many examples of collaboration failures. After a brief introduction to collaboration services, this tutorial will describe several successful deployments of state-of-the-art collaboration environments and exemplify and demonstrate the use of collaboration services to enhance human activities. We will summarize key lessons learned and report a generalized process to increase the likelihood of successful collaboration. The tutorial lasts a full day and is primarily a lecture with video demonstrations. An on-line version of the tutorial will be made accessible at http://itc.mitre.org.
